Infinite recursive loop possible w/ Solr breadcrumb generation

    XMLWordPrintable

      Description

      The Solr breadcrumb mechanism does not appear to check the level it maintains as the RI implementation does, allowing for infinite recursion in certain cases, leading to errors in Drupal when attempting to generate the breadcrumb trail.

      I have not seen this in the wild, but have managed to make it happen synthetically:

      • Create a loop in a collection structure.
      • Since breadcrumb generation uses only the first parent, adjust the collection relationships such that those which are in the loop are the first occurring in the RELS-EXT
